Perioperative antiviral therapy improves safety in patients with hepatitis B related HCC following hepatectomy

Timing of antiviral therapy in patients with hepatitis B virus related hepatocellular carcinoma undergoing hepatectomy

Globally, hepatocellular carcinoma (HCC) is among the most prevalent and deadly cancers. Hepatitis B virus (HBV) infection is an important etiology and disease progression factor for HCC. Hepatectomy is a widely accepted curative treatment for HCC, but the long-term survival rate is still unsatisfactory due to the high recurrence rate after resection. Preoperative or postoperative antiviral therapy plays an important role in improving the prognosis for HBV-related HCC patients who underwent hepatectomy. However, many patients miss out on the chance to receive long-term preoperative antiviral medication because their HBV and HCC infections are discovered concurrently, necessitating the start of remedial antiviral therapy in the perioperative phase. Therefore, it is of great value to know when antiviral therapy is more appropriate and whether perioperative rescue antiviral therapy can achieve the effect of preoperative long-term antiviral therapy.

Perioperative remedial antiviral therapy in hepatitis B virus-related hepatocellular carcinoma resection: How to achieve a better outcome

BACKGROUND

Although the benefits of antiviral therapy for hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) have been proven, researchers have not confirmed the differences in patient outcomes between patients who received preoperative antiviral therapy for a period of time (at least 24 wk) and patients who received remedial antiviral therapy just before radical resection for HBV-related HCC.

AIM

To investigate the efficacy of perioperative remedial antiviral therapy in patients with HBV-related HCC.

METHODS

A retrospective study of patients who underwent radical resection for HBV-related HCC at the First Affiliated Hospital of Xi'an Jiaotong University from January 2016 to June 2019 was conducted. Considering the history of antiviral therapy, patients were assigned to remedial antiviral therapy and preoperative antiviral therapy groups.

RESULTS

Kaplan-Meier analysis revealed significant differences in overall survival (P < 0.0001) and disease-free survival (P = 0.035) between the two groups. Multivariate analysis demonstrated that a history of preoperative antiviral treatment was independently related to improved survival (hazard ratio = 0.27; 95% confidence interval: 0.08-0.88; P = 0.030).

CONCLUSION

In patients with HBV-related HCC, it is ideal to receive preoperative long-term antiviral therapy, which helps patients tolerate more extensive hepatectomy; however, remedial antiviral therapy, which reduces preoperative HBV-DNA levels to less than 4 Log10 copies DNA/mL, can also result in improved outcomes.

Adjuvant Transarterial Chemoembolization Plus Immunotherapy for Huge Hepatocellular Carcinoma: A Propensity Score Matching Cohort Study

Purpose

The prognosis of patients with huge hepatocellular carcinoma (huge HCC, diameter ≥10 cm) is poor owing to the high early recurrence rate. This study aimed to explore the clinical value of postoperative adjuvant transarterial chemoembolization (PA-TACE) plus programmed cell death-1 (PD-1) inhibitors for huge HCC.

Patients and Methods

Data from consecutive huge HCC patients treated with hepatectomy during June 2017 and July 2022 were retrospectively collected. Baseline differences were balanced between huge HCC patients who underwent PA-TACE with (AIT group) or without PD-1 inhibitors (AT group) by propensity-score matching (PSM). We compared recurrence-free survival (RFS), overall survival (OS) and recurrence patterns between the two groups. Independent risk factors for RFS and OS were confirmed by Cox regression analysis, and subgroup analysis was also conducted.

Results

A total of 294 patients were enrolled, and 77 pairs of patients in the AIT and AT groups were matched by PSM. The 1-year and 2-year RFS were 49.9% and 35.7% in the AIT group compared to 24.7% and 15.5% in the AT group respectively (p<0.001). The 1-year and 2-year OS were 83.6% and 66.9% in the AIT group compared to 50.6% and 36.8% in the AT group respectively (p<0.001). There were no significant differences in recurrence patterns between the two groups. Multivariable analysis demonstrated that combined therapy of PA-TACE plus PD-1 inhibitors was a protective factor related to both RFS and OS.

Conclusion

PA-TACE plus PD-1 inhibitors could improve survival outcomes for huge HCC patients.

Post-transplant hepatitis B virus reactivation impacts the prognosis of patients with hepatitis B-related hepatocellular carcinoma: a dual-centre retrospective cohort study in China

BACKGROUND

Highly active hepatitis B virus (HBV) is known to be associated with poor outcomes in patients with hepatocellular carcinoma (HCC). This study aims to investigate the relationship between HBV status and HCC recurrence after liver transplantation.

METHODS

The study retrospectively analyzed HCC patients undergoing liver transplantation in two centres between January 2015 and December 2020. The authors reviewed post-transplant HBV status and its association with outcomes.

RESULTS

The prognosis of recipients with hepatitis B surface antigen (HBsAg) reappearance ( n =58) was poorer than those with HBsAg persistent negative ( n =351) and positive ( n =53). In HBsAg persistent positive group, recipients with HBV DNA reappearance or greater than 10-fold increase above baseline had worse outcomes than those without ( P <0.01). HBV reactivation was defined as (a) HBsAg reappearance or (b) HBV DNA reappearance or greater than 10-fold increase above baseline. After propensity score matching, the 5-year overall survival rate and recurrence-free survival rate after liver transplantation in recipients with HBV reactivation were significantly lower than those without (32.0% vs. 62.3%; P <0.01, and 16.4% vs. 63.1%; P <0.01, respectively). Moreover, HBV reactivation was significantly related to post-transplant HCC recurrence, especially lung metastasis. Cox regression analysis revealed that beyond Milan criteria, microvascular invasion and HBsAg-positive graft were independent risk factors for post-transplant HBV reactivation, and a novel nomogram was established accordingly with a good predictive efficacy (area under the time-dependent receiver operating characteristic curve=0.78, C-index =0.73).

CONCLUSIONS

Recipients with HBV reactivation had worse outcomes and higher tumour recurrence rates than those without. The nomogram could be used to evaluate the risk of post-transplant HBV reactivation effectively.

Conversion therapy for initially unresectable hepatocellular carcinoma: Current status and prospects

Research has shown that locoregional and/or systemic treatments can reduce the tumor stage, enabling radical surgical resection in patients with initially unresectable hepatocellular carcinoma. This is referred to as conversion therapy. Patients who undergo conversion therapy followed by curative surgery experience a significant survival benefit compared to those who receive chemotherapy alone, those who are successfully downstaged with conversion therapy but not treated with surgery, or those who are treated with upfront surgery. Several treatments have been studied as conversion therapy. However, the success rate of conversion varies greatly, ranging from 0.8% to 60%. Combined locoregional plus systemic conversion therapy has demonstrated significant clinical advantages, with a conversion rate of up to 60%, an objective remission rate of 96% for patients, and a disease control rate of up to 100%. However, patients who underwent conversion therapy experienced significantly more complications than those who underwent direct LR without conversion therapy. Conversion therapy can cause hepatotoxicity, bone marrow suppression, local adhesions, increased fragility of blood vessels and liver tissues, and hepatic edema, which can increase the difficulty of surgery. In addition, criteria need to be established to evaluate the efficacy of conversion therapy and subsequent treatment. Further clinical evidence in this area is urgently needed.

Association of hepatitis B virus DNA levels with efficacy and safety outcomes in patients with hepatitis B virus-associated advanced hepatocellular carcinoma receiving tyrosine kinase inhibitor plus anti-PD-1 antibody: a multicenter propensity-matched study

BACKGROUND

The efficacy and safety of tyrosine kinase inhibitors (TKIs) combined with anti-PD-1 antibodies (α-PD-1) in advanced hepatocellular carcinoma (HCC) with high hepatitis B virus (HBV) DNA levels (>500 IU/mL) remain unclear.

METHODS

We retrospectively assessed patients from seven medical institutions diagnosed with HBV-related HCC, undergoing treatment with TKIs and α-PD-1 in conjunction with antiviral therapies. Based on HBV-DNA levels, patients were categorized into either high (HHBV-DNA, >500 IU/mL) or low HBV-DNA (LHBV-DNA, ≤500 IU/mL) cohorts Propensity score matching (PSM) was used to minimize baseline imbalance between groups.

RESULTS

149 patients were included, with 66 patients exhibiting HBV-DNA > 500 IU/mL and 83 patients presenting HBV-DNA ≤ 500 IU/mL. Compared with the LHBV-DNA cohort, the HHBV-DNA cohort had a greater incidence of serum HBeAg positivity, tumor diameter ≥ 10 cm, and vascular invasion. Following PSM, 57 individuals were enrolled in each group. Oncological outcomes were comparable between HHBV-DNA and LHBV-DNA cohorts before and after PSM. Before PSM, the median PFS and OS were 6.1 months and 17.5 months in the HHBV-DNA cohort and 6.7 months and 19.3 months in the LHBV-DNA cohort (all P > 0.05). After PSM, the median PFS and OS were 6.0 months and 19.5 months in the HHBV-DNA cohort and 6.0 months and 17.1 months in the LHBV-DNA cohort, respectively (all P > 0.05). Safety profiles were equivalent across cohorts with no fatal incidents reported. Seven patients (4.7 %) had HBV reactivation. 1 (0.7 %) from HHBV-DNA and 6 (4.0 %) from LHBV-DNA (P = 0.134). Only one patient developed HBV-related hepatitis.

CONCLUSIONS

The effectiveness and safety of TKIs plus α-PD-1 in advanced HCC with HBV-DNA > 500 IU/mL were not compromised in the context of concomitant antiviral therapy.

Risk of HBV reactivation during therapies for HCC: A systematic review

BACKGROUND AND AIMS

Treatment for HCC has evolved rapidly, but the risk of HBV reactivation to new therapies is unclear. We systematically reviewed data on HBV reactivation in patients receiving HCC therapy in relation to use of HBV antiviral prophylaxis.

APPROACH AND RESULTS

A literature search was performed to identify all published studies including HBsAg-positive patients with HCC providing data on HBV reactivation. Forty-one studies with 10,223 patients, all from Asia, were included. The pooled HBV reactivation rate was 5% in patients receiving no specific HCC therapy and was higher in patients undergoing surgical resection (16%), transarterial chemoembolization (19%), or radiotherapy (14%) and intermediate in patients treated with local ablation therapy (7%) or systemic agents (7%). HBV reactivation rates were higher in those without compared to those with HBV prophylaxis (ablation, 9% versus 0%; resection, 20% versus 3%; chemoembolization, 23% versus 1%; external radiotherapy alone, 18% versus 0%; systemic therapy, 9% versus 3%). HBV-related biochemical reactivation rates varied between 6%-11% and 2% in patients receiving HCC therapies with high and intermediate HBV reactivation risk, respectively. Liver decompensation and death were rarely reported (0%-3%) and only in patients receiving HCC treatment with high HBV reactivation risk.

CONCLUSIONS

HBsAg-positive patients with HCC are at high or intermediate risk of HBV reactivation depending on the type of HCC therapy. Nucleos(t)ide analogue prophylaxis reduces the risk of HBV reactivation, practically eliminates the risk of hepatitis flare, and should be administered regardless of HCC treatment.

Preoperative Management of Gastrointestinal and Pulmonary Medications: Society for Perioperative Assessment and Quality Improvement (SPAQI) Consensus Statement

Perioperative medication management is integral to preoperative optimization but remains challenging because of a paucity of literature guidance. Published recommendations are based on the expert opinion of a small number of authors without collaboration from multiple specialties. The Society for Perioperative Assessment and Quality Improvement (SPAQI) recognized the need for consensus recommendations in this area as well as the unique opportunity for its multidisciplinary membership to fill this void. In a series of articles within this journal, SPAQI provides preoperative medication management guidance based on available literature and expert multidisciplinary consensus. The aim of this consensus statement is to provide practical guidance on the preoperative management of gastrointestinal and pulmonary medications. A panel of experts with anesthesiology, perioperative medicine, hospital medicine, general internal medicine, and medical specialty experience was drawn together and identified the common medications in each of these categories. The authors then used a modified Delphi approach to review the literature and to generate consensus recommendations.

Nucleos(t)ide analogues and Hepatitis B virus-related hepatocellular carcinoma: A literature review

Hepatitis B virus is mainly considered to cause hepatocellular carcinoma which is the fourth leading cause of cancer-related mortality worldwide. Treatment of Hepatitis B virus with nucleos(t)ide analogues can decrease the progression of the disease and subsequently decreases the incidence of hepatocellular carcinoma. In this review, we have discussed the different classes of nucleos(t)ide analogues used in the treatment of Hepatitis B virus and their relationship with the development of hepatocellular carcinoma. Furthermore, we discussed the effect of treatment of Hepatitis B virus with Nucleoside analogues (NAs) before, during and after surgery, chemoembolization, radiofrequency ablation, and chemotherapy for the treatment of hepatocellular carcinoma.

Neoadjuvant and adjuvant treatment strategies for hepatocellular carcinoma

Hepatocellular carcinoma (HCC) is the most common liver malignancy worldwide and a major cause of cancer-related mortality for which liver resection is an important curative-intent treatment option. However, many patients present with advanced disease and with underlying chronic liver disease and/or cirrhosis, limiting the proportion of patients who are surgical candidates. In addition, the development of recurrent or de novo cancers following surgical resection is common. These issues have led investigators to evaluate the benefit of neoadjuvant and adjuvant treatment strategies aimed at improving resectability rates and decreasing recurrence rates. While high-level evidence to guide treatment decision making is lacking, recent advances in locoregional and systemic therapies, including antiviral treatment and immunotherapy, raise the prospect of novel approaches that may improve the outcomes of patients with HCC. In this review, we evaluate the evidence for various neoadjuvant and adjuvant therapies and discuss opportunities for future clinical and translational research.

Acute kidney injury following the first stage of the ALPPS procedure: A case report

Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) is a novel approach for performing liver resection, and the number of clinical applications of this technique has rapidly increased within recent years. ALPPS is important in patients who have insufficient residual liver volume and cannot undergo radical hepatic resection. The most common postoperative complications of ALPPS include biliary fistula and infection. To date, postoperative acute kidney injury following ALPPS has not been reported. The current study reports the case of a 63-year-old patient with hepatitis B-induced cirrhosis who underwent the first stage of ALPPS without completion of the second step. The patient developed postoperative acute kidney injury following ALPPS. The present case study suggests that the use of ALPPS in patients at risk of chronic renal damage should be approached with caution in order to avoid postoperative acute kidney injury. Furthermore, improvements in surgical techniques and skills of the surgeons performing the procedure are required to reduce the surgery duration and improve patient outcomes.

42,573 cases of hepatectomy in China: a multicenter retrospective investigation

Hepatectomy is currently routinely performed in most hospitals in China. China owns the largest population of liver diseases and the biggest number of liver resection cases. A nationwide multicenter retrospective investigation involving 112 hospitals was performed, and focused on liver resection for patients with hepatocellular carcinoma (HCC). 42,573 cases of hepatectomy were enrolled, and 18,275 valid cases of liver resection for HCC patients were selected for statistical analysis. The epidemiology of HCC, distribution of hepatectomy, postoperative complications and prognosis were finally analyzed. In the 18,275 HCC patients, 81% had hepatitis B virus infection and 10% had hepatitis C virus infection. 38% of the HCC patients had normal Alphafetoprotein (AFP) level, and other 35% had an AFP level lower than 400 ng mL^-1. In the study period, 97% of the hepatectomy for HCC were treated with open surgery, and 23.81% had vascular exclusion techniques. The operation time was (191.7±105.6) min, the blood loss was (546.0±562.8) mL, and blood transfusion was (543.0±1,035.2) mL. The median survival for HCC patients was 631 days, with 1-, 3-, and 5-year overall survival of 73.2%, 28.8% and 19.6%, respectively. Liver cirrhosis, multiple nodules, tumor thrombosis and high AFP level were risk factors that affect postoperative survival.
